I am searching for any information available on Jose Augustin Quintero 1829-1885. He was a former law partner of Mirabeau Lamar. He initially enlisted with the Quitman Rifle Brigade in 1861. He was later commissioned as a Confidential Agent of the Confederacy and sent to Mexico. He is my GG Grandfather and I am researching his history. After the war he settled in New Orleans for the remainder of his life.
